March 2025 monthly summary for RabbyHub/Rabby: Implemented a critical JSON-RPC protocol fix in the CustomTestnetService by ensuring the 'params' field is always defined as an empty array for eth_chainId calls. This prevents malformed requests when 'params' is omitted and aligns with the JSON-RPC specification, reducing error rates on testnets. Key achievements: - Fixed JSON-RPC 'params' default to [] for eth_chainId (commit 6279fbb9ee3fe868b5e8e6ad0d129c8baa42d474, related to #2863). - Improved reliability and protocol conformance of testnet RPC calls, lowering support churn and integration issues for developers. - Clearer request formatting that simplifies testing and tooling interactions with Rabby on custom testnets. Overall impact and accomplishments: - Enhanced stability of JSON-RPC requests, leading to fewer failed eth_chainId calls and smoother developer experience for dApps interfacing with Rabby testnets. - Strengthened code quality around protocol handling and input normalization. Technologies/skills demonstrated: - JSON-RPC protocol compliance and defensive coding (defaulting undefined params to an empty array). - JavaScript/TypeScript codebase familiarity, commit-driven changes, and adherence to repository standards. - Change impact through targeted bug fix with clear traceability to issue #2863.
